INTRODUCTION
Updated Definition of Stroke for the 21st Century is that stroke should be broadly used in all of the following: CNS infarction, ischemic stroke, silent CNS infarction, intracerebral hemorrhage, stroke caused by intracerebral hemorrhage, silent cerebral hemorrhage, subarachnoid hemorrhage, stroke caused by subarachnoid hemorrhage, stroke caused by cerebral venous thrombosis, not specified - stroke.
Stroke itself characterized as a neurologic deficit attributed to an acute focal injury of the central nervous system by a vascular The word AustrokeAy first introduced by William Cole in 1689 in an essay called AuA Physico-medical essay concerning the late frequencies of apoplexiesAy.
Before Cole a very acute non-traumatic brain injuries were described as AuapoplexyAo, a term introduced by Hippocrates in circa 400 BC.
In 1950s, the physicians need another term to describe a temporary vascular related episodes of brain dysfunction that would not qualify as strokes, and then the term AuTransient Ischemic AttackAy came into use.
Even then the World Health Organization have its own term of strokes, which is a Aurapidly developing clinical signs of focal .

disturbance of cerebral function, lasting for more than 24 hours or leading to death, with no apparent cause other than that of vascular origin.
Ay This term was used since 1970 until present.
Even though we all know that the brain injury can occurred for less than 24 hours, so this definition of stroke by WHO is actually obsolete.
Ischemic stroke defined as an episode of neurological dysfunction caused by focal cerebral, spinal, or retinal infarction.
1 The most common neurological deficits found in stroke patient were paresis, speech, and sensory deficits.
Clinical characteristics of stroke may be varied for different population groups, but male subjects most likely experiencing the gait disturbances.

The most common conservative therapy for patients diagnosed with stroke were antiplatelet drugs such as clopidrogel and aspirin, but this therapy have major systemic bleeding side effect.
Despite the risk, this line of therapy is still being used as conservative therapy, and it seems the combination of antiplatelet such as aspirin and clopidrogel proved more effective than a single aspirin therapy itself.
To measure muscle strength, there are some quantitative methods such as dynamometers and qualitative methods which is Manual Muscle Strength (MMT).
The usage of dynamometer is not suitable for weak muscles and movement measurements with resistance.
The MMT measurements method first developed by Lovett and described by Wright in 1912 and had been revised, advanced and promoted to be a wide range of methods.
One of the revised method which was most widely accepted and used in this study, was proposed by Medical Research Council (MRC).
The original MRC scales were described as follows: 0 = no muscle contraction detected.
1 = flicker or trace contraction were detected.
2 = active movement detected but the ability against gravity were eliminated.
active movement and the ability against gravity were detected.
4 = active movement with ability against gravity and resistance were detected.
normal muscle strength detected.
Motor disability can be caused by an ischemic lesion in motor cortex, premotor cortex, motor tract, or any associated pathway in cerebral or cerebellum organ.
7 The motor cortex coordinate movement through corticospinal neuron directly or through projection against different nucleus in brain stem that elongated through spine.
Thrombosis play an important role in ischemic stroke pathogenesis.
7 Various thrombolytic therapy regimen is used to obtain higher cerebral perfusion after ischemia.

data from European Cooperative Acute Stroke Study (ECASS) i and the Safe Implementation of Thrombolysis in Stroke - International Stroke Treatment Registry (SITS-ISTR) showed that intravenous rtPA is an effective therapy to improve the outcome of patients with ischemic stroke if given within 3 until 4,5 hours after stroke onset.

Unfortunately, not many patients could have the thrombolytic treatment after stroke attack.
In Gatot Soebroto Army Central Hospital, 57,33% stroke patients came in at chronic phase (> 30 day.
Thus, new therapeutic strategies with a wider window time will be very useful to reduce ischemic morbidity in chronic phase.
Intra Arterial Heparin Flushing (IAHF) modified Digital Subtraction Angiography (DSA) in Gatot Soebroto Army Central Hospital showed a clinical improvement in chronic stroke patients Heparin usually used as flushing solution for catheterization.
11 Heparin have a role not only as an anticoagulant but also as a fibrinolytic.
Heparin increases plasminogen conversion into plasmin by stimulating tissue plasminogen activator.

Intravascular studies showed that heparin therapy can reduce the clot size, suggested its potency in brain reperfusion after ischemic.

DISCUSSIONS
Motoric function assessments were used as one of diagnostic methods for diagnosing a prognostic outcome in Multiple Sclerosis.
Stroke, or patients in Intensive Care Unit (ICU).
25-27 As a prognostic assessment method for stroke patients.
MMT with lower score show a bad prognostic outcome.
Another method to assess muscle strength is a quantitative methods using instrument such as Dynamometry.
29 In this study we measured the subjectAos motoric strength using MMT-MRC scoring system.
This method has been proved to be effective to determine muscle strength degree in stroke patients.
30 This method was also the only method to assesAo muscle strength and the level of paresis in patients with peripheral nerve lesion.
The motoric function of our body is managed by motor cortex in our brain.
In stroke patients with paresis, the neuron output impulse was decreased because of the decrease of motor neurons pool ability to move targeted motoric unit.
In anatomical perspective, there are two main components in motor cortex that play important roles for motoric function, including primary motor cortex (M.
and secondary motor cortex which was divided into Posterior Parietal Cortex (PPC).
Premotor Cortex, and Supplementary Motor Area (SMA).
M1 triggers the neural impulses that control the final execution of motoric unit, then the PPC change the incoming visual information into a motoric command, and the Premotor Cortex roles as a sensory guidance of a movement which coordinates the body orientation against the movement itself, and the last one is SMA, responsible to coordinate and plan the complex motor movements and coordinate our both hands The pathway of neuron impulse itself to stimulate a muscle contraction starts from primary motor cortex then conducted through corticospinal tract out from the spinal nerve through the cervical column cavity then the peripheral motor neuron Published by DiscoverSys | Bali Med J 2016.

relays the signals into the arms region to activate the myofibrils group located in biceps until a muscle contraction happened in that location.
Muscle weakness in chronic stroke patients might be associated with the decline of descending impulse input from motor area in brain hemisphere affected by stroke, disturbance of muscle activation, and muscle atrophy.
The EMG examination shows that patients with chronic hemiparesis has a different muscle activation pattern that differs according to the muscle contraction.
The motor contraction abnormality itself caused by troubled descending motor tract, this might explain the imbalance of muscle activities on post stroke patients.
Thus, extremities muscle weakness in patients with chronic hemiparesis caused by neuromuscular performance changes.
Lesion in motor cortex especially in M1 region in stroke accident and brain trauma will ended up as necrosis in focal area that finally will cause the loss of M1 output to spinal cord and in the end will cause functional disability.
33 The normal function of muscle needs an intact connection along the motor pathway .

, damage in any point will decrease the brain ability to control muscle movement.
The decline of this ability will cause weakness which also called paresis.
MMT is a reliable diagnostic tool to measure muscle weakness on stroke patients.
In this study the MMT score was found significantly increased after IAHF treatment.
This treatment could induce a better motor cortex function especially within the area where stroke induced lesion disturbing the motor pathway.
When the motor pathway was fixed, the neuronal output impulse will be recovered, thus the muscle strength will be increased, showed by increased MMT scores.
